Backported Features

We identified a new InnoDB feature that we released in MariaDB Community Server over the last few months that has now reached maturity and is ready for enterprise use.

Now available in MariaDB Enterprise Server 10.6:

  • Starting with this release, the number of undo logs can be reconfigured for MariaDB Enterprise Server instances after install.
    • The number of undo logs is configured by the InnoDB system variable --innodb-undo-tablespaces.
    • Splitting undo logs over multiple tablespaces can reduce the size of a single tablespace, especially the InnoDB system tablespace.
    • In previous releases, the number of undo logs had to be configured before InnoDB was initialized, so changing the number of undo logs would require setting up a new server instance. With this backport from MariaDB Community Server 10.11, the number of undo logs can be changed so it will take effect with the next server start.

Other Release Updates

We have several other maintenance items included in these releases.

MariaDB Enterprise Server 10.6.12-7
  • MariaDB Enterprise Server 10.6.12-7 Release Notes
  • Notable Changes:
    • The names used by INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION.NAME for undo tablespaces have been changed.
      • Starting with this release, names for the undo tablespaces use the format undo001.
      • In previous releases, names for the undo tablespaces used NULL.
    • For MariaDB Enterprise Cluster SST with MariaDB Enterprise Backup backup execution (namely the block DDL phase) has been changed. In previous releases, the node was paused from the cluster, generating the following log file entry: WSREP: Shifting SYNCED -> DONOR/DESYNCED.

      • JSON_PRETTY() has been added for compatibility as an alias.

Why MariaDB Enterprise Server

MariaDB Enterprise Server is an enhanced, hardened and secured version of MariaDB Community Server that delivers enterprise reliability, stability and long-term support as well as greater operational efficiency when it comes to managing large database deployments for business and mission critical applications. MariaDB Enterprise Server offers additional features needed for production workloads that are not available in the community edition, such as enterprise audit and enterprise backup, and also backports certain enterprise features to older versions so customers can take advantage of critical fixes and features immediately instead of having to upgrade to the newest version.

Being able to backport features from newer release series to older versions is a key advantage of MariaDB Enterprise Server. Quality assurance and internal processes do not always allow customers to upgrade production environments to the newest and greatest release series, although some of the new features would be of value. MariaDB Enterprise Server can help in this case, as we can backport highly requested features to existing versions in cases where we can assure that a backported feature does not decrease the stability of that release series of MariaDB Enterprise Server.
